MITEB-BOX.

Specification of Letters Patent.

Patented Apr..10, 1917.

Application filed August 29, 1918. Serial No. 117,509.

To all whom it may concern:

Be it known that I, HERBERT AnRAMsoN, a citizen of the United States, residing at Benson, in the county of Swift and State of Minnesota, have invented new and useful Improvements in Miter-Boxes, of which the following is a specification.

This invention relates to certain novel and useful improvements in miter boxes.

In carrying out the present invention, it is my purpose to provide a miter box which may be adjusted so that the saw may make straight cuts, miter cuts and bevel cuts and whereby both abevel cut and a miter cu-t may be made at the same time,

It is also In purpose to provide an adjustable miter ox whereby any type of saw may be used to make the desired cut and which will embody comparatively few parts and these so arranged and correlated as to reduce the possibility of derangement to a minimum.

Another object of my invention is the provision of an adjustable miter box WhlCh, when not in use, may be taken down and folded into small compass so that the same may be readily carried about in a tool kit or the like, and which, when set up, may be readily transported from place to place so that the same may be used on a scaffold with ease and convenience.

With the above and other objects in view, the invention consists in the construction, combination "and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings:

Figure 1 is a view in side elevation of an adjustable miter box constructed in accordance with the present invention.

Fig. 2 is a top plan view of the same.

Fig. 3 is a longitudinal sectional view therethrough.

Fig. 4 is a cross sectional view through the box.

Figs. 5 and 6 are Views of details of the invention.

Referring now to the drawings in detail, 1 designates a base plate having one end mitered, and provided with a depending centrally located strip 2 extending longitudinally of the base plate and cooperating plate and the other end enlarged in cross dimension and formed with a curved edge 4. The plate 3 is formed with an opening at the center of the are upon which the edge 4 is struck and this opening alines with an opening in the base plate and passed through these alining openings is a pivot stud 5 about which the plate 3 may swing. The curved edge 4 of the adjustable plate 3 is graduated to represent the degrees of angles and the zero mark is at the center of the edge, while the other marks increase progressively from the center toward the outer end of the curved edge of said plate. cured to the upper surface of the adjustable plate 3 adjacent to the curved edge 4 is a curved bar 6 having the upper edge formed with notches 7 corresponding to the graduations on the curved edge 4. Fixed to the plate 1 at the longitudinal center line thereof is a spring arm 8 provided with a depending ear 9 designed to engage in any one of the notches 7 to hold the plate 3 in the desired adjusted position upon the base and to indicate the angle at which the adjustable plate is disposed. Hinged to' the edge of the adjustable plate 3 beyond the base plate 1 is a plate 10 of less longitudinal and cross dimensions than the plate 3 vand adapted to overlie the latter. The edge of the plate 10 remote from the hinged edge thereof is formed to provide a tooth 11, while pivoted upon the adjustable plate 3 adjacent to the toothed end of the plate 10 is a notched bar 12 normally held in engagement with the tooth 11 by a spring 13 so as to hold the plate 10 in the desired angular position with respect to the adjustable plate 3. Connected to the plate 10 and upstanding therefrom is an arm 14 having the upper end portion bent in the direction of the curved edge of the plate 3 and connected to the upper end of the arm 14 is a curved bar 15 having the lower end formed with notches 16 corresponding with graduated plate in proper position.

marks 1'? indicative of angles. l-liin ed to the hinged end of the plate 10 is one end of rigid arm 18 connected to the other end of the arm 18 is one end or" a spring arm 19 spaced apart from the rigid arm l8 and lying parallel therewith, to the ends of the rigid arm 18 and "the spring arm 19 adjacent to the plates 3 10 are saw guides 26 normally held in face to face contact I under the action of the spring arm 19. Formed on the arm 13 ad iacent to the upper end thereoi is an outwardly projecting our 21 provided with an opening through which the bar 15 works and pivoted upon the arm 18 immediately below the ear is a spring finger 22 formed with an upwardly projecting lug 23 adapted to enter the adjacent notch 16 in the curved bar 15 to hold the saw guides in the desired angular position. The notched bar 12 is graduated as at 2% to indicate the angle at which the plate 10 is disposed.

in practice, when-it is desired to cut the timber square, the base plate 1 is placed upon the timber and the strip 2 engages the adjacent edge of the timber to hold the base The plate 3 is adjusted upon the base plate 1 to bring the zero marl: on the curved edge thereof in line with the ear 9 on the spring arm 8 and the ear engaged with the corresponding notch to hold the plate 3 in'adjusted position. The plate 10 is swung back upon the plate 3 to the zero position and the tooth 11 engaged with the notch in the bar 12 corresponding to the zero, while the arm 18 is swung relatively to the bar 15 to the zero position and the lug 23 on the spring finger 22 engaged with the notch corresponding with the zero position on the bar 15. The saw guides 20 are now in a position to hold the saw so that a square out may be made. To obtain a miter cut, the adjustable plate 3 is swung to the desired angular position upon the base place and the saw guides adjusted to correspond to the 90 degree mark on the bar 15 and the saw operated in the guides 20. To obtain a bevel cut, the saw guides 20 are adjusted to the desired angular position and the lug 23 on the spring finger 22 engaged with the adjacent notch in the bar 15 to hold the guides in such angular position.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that l have provided a miter box whereby square cuts, miter cuts and bevel cuts may be made and whereby bevel and miter cuts may be made at the same time.

While l have herein shown and described the preferred form of my invention by Way of illustration, 1 wish it to be understood that it do not limit or confine myselt to the Secured delineated, as 11 may be made within the scope of as out departing from the of the invention.

on one end of said arm engaged with said notched bar to hold said plate in adjusts position, a second plate mounted upon the first mentioned plate, a hinged connection etween the inner edge of said adjustable plate and the corresponding edge of the second named plate, a notched bar upstanding from the second named plate and yieldably mounted, a tooth formed on the second named plate engageable with said notched bar to hold the second named plate in ad justed position, and saw guides carried by said second named plate.

2. A miter box of the class described com prising a base, an adjustable plate mounted upon said base at one end thereof, a pivot stud passed through said plate and base and forming a pivot about which said adjustable plate may be swung, a notched bar on said plate at the inner end thereof, a spring arm having one end secured to said base, an ear on the other endof said arm engaged with said notched bar to hold-said plate in adjusted position, a second plate mounted upon the first mentioned plate, a hinged connection between the inner edge of said adjustable plate and the corresponding edge of the second named plate, a notched bar upstanding from the second named plate and yield ably mounted, a tooth formed on the second named plate engageable with said notched bar to hold the second named plate in adjusted position, saw guides carried by said second named plate, a hinged connection be tween said saw guides and the second named plate whereby the saw guides may be swung to the desired angle, and means carried by the second named plate and engagi ing said saw guides to hold the latter in adjusted position.

3. A miter box including a base, a pivoted plate upon the base at one end thereoi and having its inner end widened and of an arcuate formation, an arched notched bar upon the said arcuate end of the plate, a spring pressed member car iod by the base and engaging between the notches of the bar, a second plate hingedly secure t to the first mentioned plate and having an extending codification and i i. miter box of the class described coinprising a base, an ad ustable mounted ltd ond mentioned plate, guide means upon the saw guide for the notched arcuate arm, and spring pressed means carried by the rigid 10 arm of the saw guide and engaging with the notches of the said arcuate arm.

In testimony whereof I afiix my signature.
